Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a timer device suitable for insertion between a commercial AC power terminal, ie, a jack (or outlet), and an electronic device, ie, a controlled device, such as a radio.

Conventional timer devices are generally equipped with two jacks, and if a flag from an electronic device such as a radio is inserted into one of the jacks, the timer device's preset time will be activated. If power is supplied to the electronic device (power on) and the plug is inserted into the other jack, the power supply to the electronic device will be cut off (power off) at a preset time. Near these jacks, there are signs attached indicating their respective functions, such as ``Turn on at set time'' and ``Turn off at set time.''

However, in this timer device, these jacks are generally provided on the back or side of the device case, so there is a problem in that it is unclear at first glance what function the jack is connected to the electronic device. There is.

In order to avoid such problems, a single long jack is used, and after shallowly inserting the plug of the electronic device into it, the jack is rotated clockwise or counterclockwise together with the plug, and then By inserting the plug deeply into the jack, the function of this jack can be changed to ``turn on at the set time'' or ``off at the set time'' using the changeover switch, and at the same time, the window hole in the front of the timer device case can be turned on. It has been proposed that the function, ie, "on" or "off", is displayed within the screen.

The function of this timer device can certainly be seen from the front. However, this timer device, like the one with two jacks mentioned above, can only be set at one point in time (one point in time), and at that set time, the selection of ``on'' or ``off'' is made. It is long enough. In this case, there is a risk of incorrect operation and damage to the plug or jack.

In consideration of these points, the purpose of the present invention is to make it possible to easily determine whether the controlled device will be in the on or off state at two set times by simply selectively inserting the plug of the controlled device into the jack. , and to propose a timer device in which the timer time can be easily set.

The present invention has two set times, first and second, and is turned on (hereinafter referred to as "on") at the first set time and turned off (hereinafter referred to as "off") at the second set time.
A first jack configured (connected) so that
In the case where a timer device having a jack and displaying the first and second set times on the front of the case is configured, the selection of the plug to the first or second jack is configured. By inserting the target, whether the first and second set times are on or off is automatically switched and displayed.

It is extremely easy to manufacture and has a simple configuration compared to the previous version.

The state of connection between the power plug 8 and the first and second jacks 6 and 7 is shown in FIG. 31 in the figure
is a timer, and 32 and 33 are first and second timer switches operated by this timer.
This timer 31 is driven in synchronization with the oscillation circuit using the above-mentioned oscillator or the frequency of the commercial power supply. Although the first timer switch 32 is normally off, it is turned on at the time set by the first time setting means 9 and turned off at the time set by the second time setting means 10. It shall be. Also, the second timer switch 33 operates in a completely opposite manner to the first timer switch 32. Nao 34

A display plate 47 serving as a slider is attached so as to be movable, and is placed opposite to the first and second display sections 12 and 13 on the inner surface of the front panel 1, so that when the rotation lever 40 is rotated, the display plate 47 becomes a slider. First and second display sections 12
This is a case in which it is configured to slide along an extension line connecting 13 and 13. 48a, 48b and 4
8c are guide rollers for the display board 47, respectively. The display board 47 has a display as shown in FIG. 10, and the display sections 12 and 13 shown in FIG.
The interval l ₁ is chosen to be mutually identical to l ₂ shown in FIG. Also, l ₃ shown in Figure 10 is the first
and the sliding distance of the display plate 47 based on the rotation of the rotation lever 40, which is rotated by the conversion insertion of the plug of the controlled device into the second jacks 6 and 7. Furthermore, even in the embodiment shown in FIG.
The connection relationship between the power plug 8, timer switches 32, 33, and first and second jacks 6 and 7 is the same as that shown in FIG. Furthermore, the sixth
As in the case shown in the figure, the light emitting element 39 is connected to the third display section 1.
It is advisable to arrange it in correspondence with 4. Therefore, in this example as well, when inserting the power plug of the controlled device into the first jack 6, as shown in FIG.
ON is displayed on the second display section 12 and OFF is displayed on the second display section 13, so that the operating states of the first and second time setting means 9 and 10 can be determined at a glance.

According to the present invention described above, by selectively inserting the power plug of the controlled device into the first and second jacks 6 or 7, the tip of the power plug causes the rotary lever 40 to is rotationally controlled, and as a result, the first display section 12 and the second display section 13 are turned ON and OFF, or OFF, respectively.
and ON are automatically displayed. Therefore, by looking at these displays, it is possible to determine at a glance what state the controlled device will be in at the first set time and what state it will be in at the second set time. It is something.

That is, according to the present invention, when the power plug of a controlled device is inserted into the device, it is easy to see at a glance how the controlled device is controlled at each of the first and second set times.
