Abstract

PURPOSE:To prevent occurrence of erroneous setting regarding digits at the time of changing the setting by separately constituting a setting part for setting a number of plural figures and a control part for controlling a time limit and by constituting the setting part which comprises mutually independent units for every figure. CONSTITUTION:When a timer is assembled into a system, a setting unit 1 of a number is prepared corresponding to the number of figures of a set value required by the system. If the required number of figures of a set value of the system is, for example, 2, only setting units 1A, 1B are selected and connected together, and further connected to a control unit 3 via connector pins 4, 5. That is, since a setting part 1 is constituted as units 1A, 1B, 1C, 1D for each figure, setting units 1A, 1B corresponding to a required number of figures are combined. As a result, when numeral setting is to be changed, the third or upper figures will not be erroneously changed, enhancing the operability.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a timer device having a multi-digit setting unit composed of a thumb rotary switch for setting a numerical value.

[0002]

2. Description of the Related Art In a conventional general timer device of this type, as shown in FIG. 5, a thumb rotary switch 100 is provided, and the number of digits of a setting portion 101 for setting a numerical value is set to, for example, four digits. The control unit (not shown) in the same case 102 is configured to control the time limit based on the numerical value set by the setting unit 101.

[0003]

In the conventional timer device as described above, the number of digits of the setting unit 101 is previously determined to be, for example, 4 digits, so that the number of digits smaller than this, for example, 2 digits, is sufficient. In use, unnecessary high-order digits are wasted, resulting in high cost. In addition, when the above-mentioned two-digit set value is changed, there is a problem that an erroneous setting such that the unnecessary number of digits of the third digit or more is erroneously changed is likely to occur.

The present invention has been made in order to solve the above problems, and it is an object of the present invention to provide a timer device which can reduce costs and can prevent erroneous setting of digits when changing settings. Has a purpose.

[0005]

In order to achieve the above object, a timer device according to the present invention comprises a setting unit for setting a numerical value of a plurality of digits and a control unit for controlling a time limit based on the set numerical value. The setting unit is configured separately, and the setting unit is configured by an independent unit for each digit.

[0006]

According to the present invention, since the setting unit which is separate from the control unit is unitized for each digit, it is possible to combine as many units as the number of digits of the set value necessary for the system in which the timer device is incorporated. In addition, it is possible to avoid unnecessary use of a part of the setting section, which leads to cost reduction. Moreover, when changing the set value, unnecessary digit setting does not occur, and erroneous setting can be reliably prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 are perspective views showing an example of a timer device according to the present invention before and after mounting, respectively.

1 and 2, reference numeral 1 is a thumb rotary switch 2 (2A, 2B, 2C, 2) for setting a numerical value.
The setting unit 3 including D) is a control unit that controls the time limit based on the numerical value set by the setting unit 1, and the setting unit 1 and the control unit 3 are configured separately.

The setting unit 1 is composed of independent units 1A, 1B, 1C and 1D for each of a plurality of digits, for example, four digits. Reference numeral 4 denotes a common connector pin provided in the setting unit 1 and connected to a unit of the control unit 3 (hereinafter, referred to as a control unit). Reference numeral 5 also denotes a BCD signal provided in the setting unit 1. Is a signal connector pin for sending to the control unit 3. The setting unit units 1A to 1D have the same common connector pin 4 and signal connector pin 5 as those described above.
It is designed to be electrically connected via.

As shown in FIG. 3, the control unit 3 has a CPU 6 for controlling the time period based on the numerical value set by the setting unit 1, an output unit 7 controlled by the CPU 6, and a timed operation. The input unit 8 for resetting or the like is built in, and the time range can be changed by the time range setting rotary DIP switch 9. In FIG. 1, 10 is a timekeeping indicator light that blinks during time measurement and lights up when the time is up, 11 is a common connection terminal portion, 12 is a power supply terminal portion, and 13 and 14 are start and reset terminal portions, respectively.

The timer device having the above configuration is used as follows. First, when the timer device is incorporated into the system, the number of setting unit units 1 is prepared in accordance with the number of digits of the setting value required by the system. For example, if the required number of digits of the system setting value is 2 digits, as shown in FIG.
Select only the setting unit 1A, 1B and connect them to each other,
This may be connected to the control unit 3 via the connector pins 4 and 5.

That is, since the setting unit 1 is configured as units 1A, 1B, 1C and 1D for each digit, the setting unit units 1A and 1B having a required number of digits may be combined. As a result, when changing the numerical setting, it is not necessary to erroneously change the setting of the third digit or more as in the conventional case, and the usability is improved.

Further, since the setting unit 1 is unitized for each digit, the thumb rotary switch 2 is mounted in the mounted state.
Since the required number of digits is sufficient, wasteful incorporation can be eliminated and cost can be reduced, and it is also useful for saving the space of the entire timer device.

As described above, the setting unit units 1A and 1B
When the control unit 3 and the control unit 3 are combined and mounted in the system, the CPU 6 controls the time limit by setting the numerical values with the thumb rotary switches 2A and 2B of the setting unit 1A and 1B and starting the timer operation. Output section 7
Will output a timed signal.

By the way, in the above-mentioned embodiment, the connecting means between the setting unit 1 and the control unit 3 is constituted by the connector pins 4 and 5, but as shown in FIG. You may make it connect by the printed wiring board 43 which has the pattern 41 for commons, and the pattern 42 for signals.

[0016]

As described above, according to the present invention, since the setting unit configured separately from the control unit for controlling the time period is unitized for each digit, the setting of only the number of digits required for the system is performed. It suffices to mount the sub-units in combination, and it is possible to reliably prevent erroneous digit settings when changing settings. further,
By combining the necessary setting unit, the elements of the setting unit are not wasted, and the cost and space can be saved.
