Problems solved by technology

According to such a structure, there is a problem that the reliability of the electrical connection between the connector and the media player decreases due to external factors such as dust adhering to the exposed connector and making the electrical connection state unstable.
In addition, there is a problem that the design freedom of the projector is limited due to the structure where the connection part is always exposed.
In addition, when the media player is fixed in the state where the connector is only connected to the media player, there is a problem that the fixing of the media player tends to become unstable due to external force, etc., and the reliability of the structural connection decreases.
In addition, there is also a problem that key operations cannot be performed stably on the connected media player due to unstable fixation of the connected media player.

no. 1 Embodiment approach

[0050] figure 1 It is a functional block diagram of the projector 1 according to the embodiment. refer to figure 1 The configuration and operation of the projector 1 will be described.

[0051] Projector 1 includes: operation panel 11, operation signal processing unit 12, control unit 13, connector 50, external device connector 14, input selection unit 15, video and audio signal processing unit 16, liquid crystal light valve drive unit 17, Optical unit 18, sound output unit 19, and the like. In addition, the optical unit 18 is configured to include a light source 181 , a liquid crystal light valve 182 , a projection lens unit 183 , and the like.

[0052] The socket part 50 is provided on the moving part 40 (refer to figure 2 ), and for the portable media player 100 to connect. Furthermore, the external device connector 14 has various connectors (not shown), and can be connected to external connected devices (not shown) such as a PC (personal computer), a video tape recor...

no. 2 Embodiment approach

[0132] Next, a second embodiment will be described.

[0133] Such as Figure 9 As shown in (a), the front surface 20a is composed of an inclined surface 201a having an angle θ1 with respect to the Z-axis direction, and an inclined surface 201b having an angle θ2 on the bottom surface 20f side. The connection part 30 for mounting the media player 100 is provided so that the media player 100 may be located in the substantially center part of this front surface 20a. Additionally, if Figure 9 As shown in (b), when the media player 100 is placed on the connection portion 30, it is installed in a state substantially parallel to the inclined surface 201a (inclined to form an angle θ). The angle θ1 is set in consideration of easiness for the user to place the media player 100 on the connection portion 30 , ease of viewing the display portion 101 of the media player 100 when placed, and the like.

[0134] The housing 20 is divided by the XY plane passing the boundary between the in...

Abstract

The present invention provides a projector that improves the electrical and mechanical connection reliability of a portable media player and improves design freedom. The projector (1) is equipped with a connection part (30) for connecting the media player (100) and placing the media player (100), and the connection part (30) has a The socket part (50) on which the media player (100) is placed; the moving part (40) that holds the socket part (50) to be rotatable, and can be freely moved relative to the main body of the projector (1) ; and the driving mechanism part (sliding mechanism part (60)) that drives the moving part (40) in a mode that can be sent out and sent in freely.

Description

technical field [0001] The present invention relates to projectors. Background technique [0002] In recent years, a portable media player is connected to a speaker device or the like, and audio data stored in the media player is output as amplified audio. [0003] In Patent Document 1, it is disclosed that a portable media player is connected to a connection unit configured on a projector, and the image data stored in the media player is enlarged and projected from the projector to a projection screen as an image. Audio data stored in the media player is output as audio from a speaker attached to the projector, and the like. [0004] [Patent Document 1] Specification of US Patent No. 7599177 [0005] However, in Patent Document 1, the connecting portion is configured to be fixed to a predetermined portion of the projector. In addition, the connector provided on the connection portion and electrically connected to the media player is always exposed to the outside. Accord...
