Image reading and recording apparatus

Abstract

An image reading and recording device. The scanning unit is rotatably arranged to the recording unit. The recording unit and the scanning unit are coupled to each other using a damper unit including a holder, a rod and a spring. The damper unit is arranged such that the action direction of the spring is switched during the opening and closing process of the scanning unit. A guide surface capable of abutting against a protrusion arranged on the rod is provided in the recording unit. During the movement of the scanning unit from its open position to its closed position, the protrusion abuts against the guide surface before the direction of action of the spring is switched.

Description

technical field [0001] The present invention relates to an image reading and recording apparatus composed of a combined recording unit and a scanning unit, and more particularly to a mechanism for opening and closing the scanning unit relative to the recording unit. Background technique [0002] There has been a conventional image reading and recording device composed of a combined recording device and a scanner. The recording apparatus here records an image onto a recording material with a recording head based on image information. The scanner reads an image on an original with a reading unit such as a CCD, and outputs the read image signal. An image reading and recording device is generally adapted to mount a scanning unit on a recording unit, which is a recording device, in a state where the scanning unit can be opened and closed. The image reading and recording apparatus is adapted to move up the scanning unit for maintenance such as replacing a recording head or an in...

Problems solved by technology

Therefore, the above method of distributing the spring force by abutting the assembly shaft 105a of the rod 105 against the recess 106a of the holding case 106 cannot obtain a necessary and sufficient cushioning effect.

That is, a buffering effect sufficient to sufficiently reduce the speed of the scanning unit when the scanning unit is turned off cannot be obtained, and the scanning unit finally hits the recording unit at a considerable speed

Therefore, it is difficult to reduce or avoid shocks in the closed position

[0013] In this case, there is a disadvantage that the user gets his or her hand stuck in the scanning unit 103, or that the device is damaged due to the scanning unit 103 being moved violently up to its closed position

Moreover, if another buffer unit for buffering the motion of the scanning unit 103 before its closed position is provided in order to avoid such disadvantages, the following disadvantages arise: resulting in an increase in the size of the device main body and an increase in the cost of the device
