Description

DETAILED DESCRIPTION OF THE INVENTION The operation part opening/closing lid in the remote commander of the present invention will be described in detail according to the following items.

A. Industrial field of application B1 Overview of the invention C1 Prior art [Figures 5 and 6] D1 Problem to be solved by the invention [Figures 5 to 7] E0 Means for solving the problem F. Examples [Figures 1 to 4] a. Overview [Figures 1 and 2] b. Opening/closing M [Figures 1 to 4] G1 Effects of the invention (A. Field of industrial application) Book The present invention relates to a new operating section opening/closing lid in a remote commander. Specifically, regarding an opening/closing lid that covers part or all of an operating section with a large number of operation buttons arranged, when the opening/closing lid is opened, the opening/closing lid is in a position that is removed from the top surface of the casing in which the operating section is installed. This allows the top surface of the housing to be fully utilized as the operation button arrangement area.
This allows the remote commander to be made smaller.

(B. Summary of the Invention) The operation unit opening/closing lid of the remote commander of the present invention has a sliding groove extending approximately in the front-rear direction on the side surface of the casing in which the operation unit is provided on the top surface, and one end of which reaches near the front or rear end. A support piece is provided at the end of both sides of the opening/closing lid that corresponds to the other end of the sliding groove, and the support piece protrudes toward the lower force, and the protrusion protrudes from the inner surface of the support piece Ω. The operation part is covered by the opening/closing lid when the protrusion is slidably engaged with the sliding groove, and the protrusion is located at the other end of the sliding groove, and the operation part is opened and closed when the protrusion is positioned at one end of the sliding groove. By positioning the lid so that it is off the top surface of the casing, when the opening/closing lid is opened, the opening/closing lid is retracted to a position where it is completely off the top surface of the casing, so that the top surface of the casing cannot be seen. It can be used as a placement part for full operation buttons, and therefore, even if the upper surface of the casing is small, many operation buttons can be arranged, and the remote commander can be made smaller.

(C, Prior Art) [Figures 5 and 6] Remote commanders, which can remotely control these devices, are now being used in many electronic devices such as television receivers, video tape recorders, and projectors. It's becoming.

As these devices become more multifunctional and sophisticated, the number of control items has also increased, and some devices are equipped with dozens of operation buttons.

Some of the operation buttons are not normally used, but are only used when making adjustments. Such adjustment operation buttons are not only not used during normal use, but also cause inconvenience if they are accidentally operated while other operation buttons are being operated, so they are usually covered with an opening/closing lid. Some devices have an opening/closing lid that is opened and operated only when necessary for adjustment or the like.

Figure 5 shows m pieces of such remote commanders, and the normally used operation buttons C are on the top of the housing.
and an operation button d used for adjustment.

Reference character e denotes an opening/closing lid rotatably supported at the end of the casing, and is rotatable between a closed position indicated by a two-dot chain line and an open position indicated by a solid line.

During normal use, the operating button C is used with the opening/closing lid e placed in the closed position, and when adjustment etc. is necessary, the opening/closing lid e is rotated to the open position and the operating button d is pressed.
It is intended to be in a state where it can be used.

Figure 6 is another example of a conventional remote commander with an opening/closing lid.
This shows that.

On the top surface of the casing g are arranged operation buttons h that are normally used and operation buttons i that are used only in special cases such as adjustment, and are provided with a slidable opening/closing lid j.

Opening/closing Mj is slidable between a closed position indicated by a two-point metal line and an open position indicated by a solid line, and is in the closed position during normal use, covering the operation button i.
Only when operation of the operation button i is required, such as during adjustment, is the operation button i moved to the open position and opened.

(D. Problem to be solved by the invention) [Figures 5 to 7
[Fig.
Even if an operation button is placed in the range indicated by , it will be impossible to operate or it will be extremely difficult to operate, and the area or a wider range will become an invalid part that cannot be used for arranging the operation button.

Therefore, as shown in Fig. 7, it may be possible to make the opening/closing lid e open even wider, but in order to do this, a large notch must be cut in the part of the opening/closing lid e near the pivot point. In this case, when the case is placed in the closed position as shown by the two-dot chain line, there will be a part on the top surface of the casing that is not covered by the opening/closing lid e, as shown by m. It ends up not functioning as a lid.

Furthermore, in the remote commander f shown in FIG. 6, even if the opening/closing lid j is moved to the open position, the
The part indicated by is still covered by the opening/closing lid j,
No operation buttons can be placed in this area.

In this way, in the conventional remote commander a1f, even when the opening/closing lids e, j are moved to the open position, there is a portion on the upper surface of the casing (g) that is covered by the opening/closing lids e, j and becomes an ineffective part. Therefore, the size of the housing must be increased accordingly, which is an obstacle to downsizing the remote commander.

It may be possible to construct a structure in which the opening/closing lid can be attached to and detached from the housing, but if this is done, users may get used to losing the opening/closing lid.

(E. Means for Solving the Problems) In order to solve the above-mentioned problems, the operation part opening/closing lid in the remote commander of the present invention extends substantially in the front-rear direction on the side surface of the casing on which the operation part is provided on the top surface, and has one end. A sliding groove is formed in which the portion reaches near the front end or the rear end, and a support piece is provided that protrudes substantially downward at the end of the side corresponding to the other end of the sliding groove on both sides of the opening/closing lid. , a protrusion protruding from the inner surface of the support piece is slidably engaged with the sliding groove, and with the protrusion located at the other end of the sliding groove, the operating section is covered by the opening/closing lid, and the protrusion is located at one end of the sliding groove, and the opening/closing lid is located away from the top surface of the housing.

Therefore, in the operation part opening/closing lid of the remote commander of the present invention, when the opening/closing lid is opened, the opening/closing lid is retracted to a position completely removed from the top surface of the casing, so that the entire top surface of the casing is removed from the edge. Therefore, if the area of the top surface of the housing is the same as before, it is possible to arrange a greater number of operation buttons than before. If the number of operation buttons is the same as the conventional one, the area of the top surface of the housing can be made smaller than that of the conventional one, contributing to miniaturization of the remote commander.
