Problems solved by technology

[0010] However, in terms of increasing costs, increasing the fixing force for suppressing the distortion of a hard sheet requires a strong operating force, resulting in poor operability.
[0011] (3) In the locking mechanism utilizing the knurled shape, although the above-mentioned problems can be solved, the operator needs to take off the operation part, and it is impossible to realize the operation with one finger corresponding to the disabled.

no. 1 approach

[0029] Below, refer to figure 1 , 2 , 3, 4, 5, 6, 7, 8, 9A, 9B, 9C, 10A, 10B, 11A, 11B, 12A, 12B, and 12C, Embodiment 1 of the present invention will be described. figure 1 and figure 2 is a perspective explanatory view of the recording device of the first embodiment, image 3 and Figure 4 It is a perspective explanatory view of the mechanism part of the recording device of the first embodiment, Figure 5 is a cross-sectional explanatory view of the recording device of the first embodiment, Image 6 , 7 , 8, 9A, 9B, 9C, 10A, 10B, 11A, and 11B are explanatory diagrams related to the sheet feeding device.

[0030] The recording device 1 of the present embodiment is composed of a feeding device 2 , a transport unit 3 , a discharge unit 4 , a carriage unit 5 , a cleaning unit 6 , and the like. Here, they are separated item by item, and their general situation is described in turn.

no. 2 approach

[0090] Below, refer to Figure 12A , 12B and 12C describe the second embodiment. Here, only the parts different from the first embodiment will be described.

[0091] In the first embodiment described above, the movable side guide 23 is formed of resin such as ABS, and the knurl corresponding portion 232 acts on the knurled portion 211 of the pressure plate 21 by virtue of the elasticity of the resin.

[0092] However, as shown in FIGS. 12 , 12B and 12C, it is also feasible to arrange a locking spring (loading mechanism) 238 composed of a compression coil spring or the like between the outer operating portion 233 and the inner operating portion 234 . According to such a configuration, the knurl corresponding portion 232 presses the knurled portion 211 by the urging of the above-mentioned lock spring 238 , and the knurled contact action is performed more reliably. Furthermore, even if the movable side guide 23 and the pressure plate 21 are deformed or the like, the locking fo...

no. 3 approach

[0094] Below, refer to Figure 13 A third embodiment will be described. Here, only the parts different from the first embodiment will be described.

[0095] In the first embodiment described above, the movable side guide 23 is integrally formed of a resin material, however, as Figure 13 As shown, it is also possible to form the parts that make the inner side operation part 234 and the knurled corresponding part 232 into one part, set the center of rotation, and use a locking spring 238 composed of a torsion coil spring to make the knurled corresponding part 232 and the knurled The knurled contact of portion 211.

[0096] According to such a structure, similarly to the second embodiment, the contact function of the knurl corresponding part 232 and the knurling of the knurled part 211 can be made more reliable. Furthermore, even if the movable side guide 23 and the pressure plate 21 are deformed or the like, the locking force will not be lowered. Therefore, the pitch of the...

Abstract

Provided is a sheet material guide mechanism which has an effect of restraining a sheet material from moving diagonally and is accommodating disability and being easily operated, at low cost and with a simple structure.This sheet material guide mechanism which guides the end of the sheet material includes a movable side guide 23 capable of sliding corresponding to a sheet material size and being fixed at a given position in a sliding area; a sheet material guide section 231 provided in the movable side guide 23 to regulate a sheet material position by abutting against the end of the sheet material; and an inside operating section 234 provided in the movable side guide 23 and capable of releasing a fixed condition of the movable side guide 23 by pressure force.

Description

technical field [0001] The present invention relates to a sheet guide mechanism, a sheet feeding device equipped with the mechanism, and a recording device such as a printer or a facsimile device, capable of reliably guiding a fed sheet. Background technique [0002] In the prior art, in recording devices such as printers, copiers, and facsimile machines, as sheets, in addition to plain paper, special sheets such as thick paper such as postcards or envelopes or special sheets such as plastic sheets are used. Each sheet is inserted by hand or automatically and continuously fed by a sheet feeding device. Furthermore, in the case of carrying out the feeding operation, it is necessary to restrict the above-mentioned sheet so that it can be fed and conveyed without skewing. Therefore, the feeder cooperates with the guide for stacking the sheets to restrict both sides of the sheets. [0003] Usually, the reference of the sheet is determined unilaterally, so the guide on the refe...
