2 is fitted into the slider accommodating chamber 11 so as to be movable back and forth from the rear surface of the housing 1. The slider 12 has a memory card insertion opening 12a on its front surface, and a connector 5 for inserting a memory card is attached to the inner end of its rear surface. A memory card insertion opening 1a is formed on the front surface of the slider housing chamber 11 of the housing 1, and a slider entrance / exit opening 1b is formed on the rear surface thereof. A flange 12b is formed around the memory card insertion slot 12a of the slider 12. A lid 13 is attached to the memory card insertion slot 1a.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a display device using a memory card, and particularly, its thickness is made as thin as possible.

[0002]

[Prior Art]

 An example of a display device using a memory card is an operation display device with coordinate input. This is because when you insert a memory card, the screen data stored on that card will be displayed, and according to the display screen, you can selectively touch the shapes, characters, symbols, etc. on the screen to display the coordinates. The data corresponding to the position, and thus the coordinate position, is input.

In a conventional display device of this type, as shown in FIG. 3A, a display panel 2 is mounted on the front side of a rectangular parallelepiped casing 1, and a card insertion chamber 3 is provided below the display panel 2 from the front side to the back side. Is formed, and a connector 5 for inserting the memory card 4 is attached near the inner surface thereof. The thickness (dimension in the front-rear direction) of the housing 1 was made substantially equal to the length of the memory card 4.

As another example of the related art, FIG. 3B shows that the thickness of the housing 1 is thin and the size is small, and the memory card 4 is inserted into the connector 5 and the front surface of the housing is shown. More half of it is projected.

[0005]

[Problems to be solved by the device]

 The conventional device shown in FIG. 3A has a drawback that it is thick and occupies a large space. Although the device in FIG. 3B occupies a small space, the memory card 4 projects forward, so carelessly touching the device during operation of the device may cause vibration or shock to the contact portion between the memory card 4 and the connector 5, resulting in electrical damage. There is a risk that the static connection may become unstable and noise may be generated, disturbing the display screen or causing the device to malfunction. The purpose of the present invention is to solve such a conventional drawback so that the thickness of the device is considerably smaller than the length of the memory card 4 and the memory card does not protrude from the front of the device when mounted. Is.

[0006]

[Means for Solving the Problems]

 The display device of the present invention is provided with a frame-shaped casing having a thickness smaller than the length of the memory card to be inserted, and the display panel is mounted in the casing. A slider accommodating chamber is formed by penetrating the casing in the thickness direction (front-rear direction). A slider is fitted in the slider accommodating chamber so as to be movable back and forth from the back surface of the housing. The slider has a memory card insertion opening on its front surface, and a memory card insertion connector is attached to the inner edge of the rear surface.

[0007]

【Example】

 1 and 2, parts corresponding to those in FIG. 3 are designated by the same reference numerals, and a duplicate description will be omitted. In this invention, the housing 1 of the device is in the form of a frame whose thickness is smaller than the length of the memory card to be inserted, as in the case of the conventional FIG. 3B. A thin rectangular parallelepiped slider accommodating chamber 11 is formed by penetrating the casing 1 in the thickness direction (front-back direction), and a slider 12 is fitted in the slider accommodating chamber 11 so as to be able to move forward and backward from the rear surface of the casing 1. .

The front surface of the slider 12 is opened to serve as a memory card insertion opening 12a, and the connector 5 for inserting a memory card is attached to the inner end of the rear surface. A memory card insertion opening 1a is formed on the front surface of the slider accommodating chamber 11 of the housing 1, and a lid 13 is attached thereto. Further, a slider entrance / exit 1b for advancing and retracting the slider 12 is formed on the rear surface of the slider accommodating chamber 11.

As shown in FIG. 1A, when the lid 13 is opened and the memory card 4 is inserted through the memory card insertion openings 1 a and 12 a and the tip of the memory card 4 is pushed in to fit into the connector 5, as shown in FIG. 1B. The slider 12 is guided to the slider housing chamber 11 and slid rearward from the slider entrance / exit 1b, and the flange 12b formed on the peripheral edge of the memory card insertion opening 12a of the slider 12 corresponds to the slider entrance / exit 1b of the housing 1. It comes into contact with the peripheral edge of and stops. If the memory card 4 is further pushed in this state, it is easily fitted into the connector 5, the memory card 4 is housed in the slider housing chamber 11, and the memory card insertion opening 1a is closed by the lid 13 (FIG. 1C).

When pulling out the memory card 4, when the memory card 4 is pulled, the slider 12 is slid forward together with the memory card 4 (on the side of the memory card insertion slot 1a), and the flange 12b of the slider 12 of the memory card insertion slot 1a of the housing 1 is pulled out. The memory card 4 can be easily pulled out from the connector 5 by coming into contact with the peripheral edge and stopping, and further pulling the memory card 4.

[0011]

[Effect of the device]

 According to this invention, the thickness of the display device can be made considerably smaller than the length of the memory card 4, and since the memory card does not protrude from the front surface of the device when mounted, the memory card can be carelessly operated during operation of the device unlike the conventional case. Touch and there is no danger of adversely affecting the operation of the device.
