Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a clock-type display device for tabletop use, and particularly to a clock-type display device in which a clock display and an image display can be arbitrarily selected.

[Prior art and its problems]

Conventionally, watches that use a liquid crystal display element (LCD) for dial display are widely known. However, these devices only had a single function as a clock and were not used for any other purpose. On the other hand, image display devices that display images such as so-called positive films used for slides, etc., also have only a single function of displaying images.

Therefore, in the past, a clock existed separately from a display, and providing both on a table required space and was complicated.

[Means for Solving the Problems] The purpose of the present invention is to obtain a compact clock-type display device that has not only the time display function of a clock but also the function of displaying so-called positive film images such as slides. A transparent plate on which a clock face is arranged, a half mirror attached to the rear of the transparent plate, and a removable cartridge arranged at the rear of the half mirror to which a positive film can be attached. Provided is a clock-type display device comprising a surface light emitting body disposed behind the cartridge and a drive circuit for driving the clock, and selectively displaying a clock and an image. It is something.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

1 and 2 are a front view and a configuration diagram showing the internal mechanism of a clock-type display device according to the present invention.

The clock display device 1 includes inside a casing 2,
A transparent plate 3 with a clock face displaying an LCD, a half mirror 4 installed adjacent to the rear of the transparent plate 3, and a projection installed behind the half mirror 4 used for slides, etc. A cartridge 5 to which a positive film, so-called positive film, can be attached and which can be freely inserted and removed from the side of the clock display device 1.
, a surface light emitter 6 disposed behind the cartridge 5, a drive circuit 7 for driving the clock of the clock display device 1, a power source 8 for the drive circuit 7, and a switch 9. . The transparent plate 3, drive circuit 7, and power source 8 form a clock display mechanism, and the half mirror 4, cartridge 5, and surface light emitter 6 form a film display mechanism. A transparent plate 3, a cartridge 5, and a surface light emitter 6, each having a half mirror 4 adjacent thereto, are arranged parallel to the front of the casing 2 with appropriate intervals between them.

In FIG. 1, a substantially rectangular opening 2a is bored in the front of the casing 2.
The transparent plate 3 is exposed from a. By applying a voltage from the drive circuit 7 shown in FIG. 2, a liquid crystal display element (LCD) 1 disposed on the transparent plate 3
A predetermined number appears at 0 and a clock is displayed.
The drive circuit 7 for clock display is a built-in DC power supply 8
Since this is done using AC power, it is not affected by power outages, etc., as is the case when using AC power. When the clock is displayed, the surface light emitting body 6 is connected to the transparent plate 3.
This function is not provided by the half mirror 4 disposed behind the cartridge 5, and the positive film loaded in the cartridge 5 cannot be seen from the outside.

The half mirror 4 having a transmittance of about 10% can be optimally used. Further, the cartridge 5 is provided so as to be insertable and removable from the side of the casing 2, and a so-called positive film or the like can be mounted therein. Therefore, it is possible to easily load various types of positive films into the cartridge 5 and display and enjoy the images. For example, a dry cell battery can be used as the power source 8, and can be easily replaced by opening the back cover 2b of the casing 2.

A method of using the clock-type display device 1 of the present invention configured as described above will be explained.

When using the clock display function, when the switch 9 is turned on and the drive circuit 7 and the crystal display element 10 are connected, a time display appears on the opening 2a of the casing 2 by the liquid crystal display element 10. At this time, the positive film mounted on the cartridge 55 is not visible from the outside due to the half mirror 4 adjacent to the rear of the transparent plate 3. On the other hand, when using the image display function of the positive film loaded in the cartridge 5, the switch 9 is in an OFF state, and the inside of the casing 2 is dark, with only the surface light emitter 6 projecting light. That is, the cartridge 5 is placed behind the cartridge 5.
A positive film mounted on the cartridge 5 is irradiated by a surface light emitter 6 provided in parallel with the light emitting member 6 . As a result, the film image is visible on the outside of the casing 2 through the half mirror 4 and the transparent plate 3.

FIG. 3 is a front view showing another embodiment of the present invention. In the figure, an opening 2a of a casing 2 of a timepiece display device 1 is divided into two parts, and a liquid crystal display element 10 is disposed on a transparent plate 3 in one of the divided parts, as in the first embodiment. It is set up. A voltage is applied to this liquid crystal display element 10 from a drive circuit (not shown) to display time. Further, although not shown in the drawings, the other divided part includes a cartridge 5 to which a positive film is attached behind the transparent plate 3 via a half mirror 4 adjacent to the rear of the transparent plate 3;
Furthermore, a surface light emitter 6 is arranged behind it.

How to use the timepiece display device 1 configured as above will be explained.

Liquid crystal display element 1 on one of the divided transparent plates 3
0 has a built-in drive circuit that constantly displays the time. Since the inside of the casing 2 is dark, the other divided part undergoes total reflection on the transparent plate 3 and the half mirror 4, and can be used as a mirror.

Therefore, when placed on a table, it can be used in two ways: as a table clock and as a mirror. Further, by turning off a switch (not shown) to darken the inside of the casing 2, the surface light emitter 6 displays an image of the positive film loaded in the cartridge. In this case, it can be used as a display such as a positive film. In this way, the image of the positive film attached to the cartridge can be viewed only when desired, and can be used as a mirror at all times.

As described above, according to the clock-type display device 1 of the present invention, since the so-called positive film image display device and the clock device are integrated, space can be saved and the device can be configured compactly.

[Effect of idea]

As described in detail above, according to the clock type display device of the present invention, it is possible to arbitrarily display a clock display and an image display of a positive film used for slides, etc., by selection. Therefore, its use as a tabletop display is wide-ranging. Further, the positive film having the image is constructed in a cartridge type and can be freely replaced from the side end, so that the user can freely and easily attach the film.
