On the other hand, when the driving body 5 is made to retreat, the driving part comes in a state to make contact with the driven part in the signal generator 4, and the operation body 5 is made to turn in this state, the driven part of the second signal generator 4 is driven by the driving part to generate a pulse from the second signal generator 4. Thereby, two kinds of different pulse signals can be generated with good operability.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a pulse generator used in various electrical devices.

(Prior Art) Conventionally, when two different types of pulse signals are to be generated, two pulse generators are provided side by side and their operating bodies are selectively operated.

(Problems to be Solved by the Invention) In this conventional configuration, when one type of pulse is generated and then another type of pulse is generated, the operating body of each pulse generator must be changed. There was a time.

The present invention has been made in view of the above points, and its purpose is to prevent generation of other types of pulse signals after generating a 181g pulse signal.
To provide a pulse generator capable of generating other types of pulse signals by simply moving the operating body forward or backward and rotating it again while holding the operating body.

[Means to solve problems]

In order to achieve the above object, the present invention takes the measures as described in the claims above, and its effects are as follows.

[Effect]

When the operating body is moved forward, the driving section is brought into a state in which it is linked with the driven section of the first signal generator. When the operating body is rotated in this state, the driven part of the first signal generator is driven by the drive part, and a pulse signal is generated from the first signal generator. On the other hand, when the operating body is moved backward, the driving section becomes in a state of being linked with the driven section of the second signal generator. When the operating body is rotated in this state, the driven part of the second signal generator is driven by the drive part, and a pulse signal is generated from the second signal generator.

The first element 11 and the third element 13 constitute a case of the second signal generator 4, respectively. Each case element described above is provided with a bearing shaft 14.15, a bearing 16.17, etc.

Next, the first signal generator 3 will be explained.

The signal generator 3 has a structure equivalent to that shown in Japanese Patent Application Laid-Open No. 63-216223, and consists of a cam 18 and switches 19 provided on both sides of the cam 18.

The cam 18 is made of an insulating material such as synthetic resin, and is rotatable by fitting the shaft hole 20 into the support shaft 14.15. Further, the cam 18 is provided with an integrally molded retaining piece 21, which is illustrated as a driven part, on its outer periphery, a bridging piece 22 fixed to the cam, and a receiving part 23 for the biasing force.

Each of the switches 19 is provided along the rotation locus of the bridging piece 22, and is composed of a pair of contact pieces 24 and 25, each made of a material with good conductivity and spring properties.

Their base portions are fixed to the case element 12, and the portions near the tips resiliently abut against the receiving portions 23 on the cam 18 to urge the cam 18 to the normal position as shown in FIG. That's what I do.

Reference numerals 26 and 27 indicate connection terminals connected to each of the contact pieces 24 and 25, respectively.

Next, since the second signal generator 4 has the same structure as the first signal generator 3, each member is given the same reference numeral and redundant explanation will be omitted. The cam 18 in the signal generator 4 is the same as the cam 18 in the first signal generator 3.
- They are arranged on the axis, and the heights of the retaining pieces 21 are also the same.

Next, the operating body 5 will be explained. Reference numeral 28 denotes an operating shaft, which is attached to the bearings 16 and 17 so as to be rotatable and movable back and forth. Reference numeral 29 denotes a rotating body integrally formed with the shaft 28, and a large number of projecting pieces 30 are provided around the rotating body. The protruding piece 30 is
In this embodiment, this is illustrated as a driving part in the operating body 5, and its height is approximately 300 mm from the center of the operating shaft 28.
The height is such that the tip of the engagement piece 21 of the cam 18 in the normal position is located within the radius to the tip of the cam 18.

In the case of the above structure, the operating shaft 28 is rotated to the right while being pushed in as shown in FIG. 1, for example. In this state, the protruding piece 30 on the rotating body 29 is connected to the first signal generator 3.
It is in a state of interlocking with the engagement piece 21 in . Therefore, due to the rotation of the rotating body 29 due to the rotation of the operating shaft 28,
As shown in FIG. 3, the cam 18 is rotated to the left, and in this state, the engagement piece 21 is connected to the projection piece 30 that rotates one after another.
The cam 18 is repeatedly engaged and disengaged (each time the engagement piece 21 moves out of the rotation locus of the protrusion 30, the cam 18 is returned to the normal position by the biasing force of the contact pieces 24 and 25, and is engaged with the next protrusion 30). ), it swings as shown by the arrow in the figure. As a result, the bridging piece 22 is connected to both contact pieces 24, 25 on the left switch 19.
is intermittently bridged, and a pulse signal is obtained between the connection terminals 26 and 27 of the switch 19. On the other hand, operation axis 2
8 to the left in FIG. 2, the cam 18 turns to the right and performs the same operation as above, and the right switch 19
A pulse signal is obtained.

Next, the operating shaft 28 is pulled back, and the protruding piece 30 on the rotating body 29 becomes the engaging piece 21 on the second signal generator 4.
It will be in a state that is linked to. When the rotation shaft 28 is rotated in this state, pulse signals can be obtained from each switch 19, 19 of the second signal generator 4 in the same manner as in the case of the first signal generator 3. .

The pulse signals obtained from each signal generator in the pulse generator as described above can be used, for example, for the purposes shown in Table 1 below.

Table 1 Next, in the above-mentioned pulse generator, the operating shaft 2

32b is installed around the third element 13 of the case, and an engaging piece 33 is attached to the third element 13 of the case to bring it into elastic contact with the operating shaft 28, and the protruding piece 30 of the rotating body 29 is connected to the first signal generator. 3rd or 2nd
At each position of the signal generator 4 in which the engagement piece 21 of the cam 18 interlocks, the engagement piece 33 is inserted into the engagement groove 32a, 32, respectively.
The positioning of the operating shaft 2B may be achieved by engaging with the shaft 2B.

Next, FIGS. 5 to 8 show different embodiments of the present application, and FIG. 0 shows different examples of the configurations of the first and second signal generators and the relationship between them and the operating body. Each of the signal generators 3e, 4a is equipped with a rotating body 29a, and each of the rotating bodies 29e has a clutch element 35, 36, which is illustrated as a driven part. On the other hand, the operating body 5e
is equipped with a drive body 37 fixed to the operating shaft 28e, and the drive body 37 has clutch elements 38 and 39, which are illustrated as drive parts, on one side and the other side, respectively. A spring 40 is interposed between spring seats 40a40b and biases the driver 37 toward the second signal generator 4e.

Next, each of the above signal generators 3e and 4e will be explained.

These have the same structure as that shown in Japanese Patent Application Laid-Open No. 64-17341, and include the rotating body 29e and the cam 18e.
A biasing mechanism 42 is provided in addition to the switch 19e. The cam 18e is rotatably attached to the case le with a shaft 43, and has interlocking teeth 44 with the biasing mechanism 42 on the outer periphery in addition to the engagement piece 21e and the bridging piece 22e. . As shown in the figure, the tips of the contact pieces 24e and 25e of the switch 19e are positioned at different positions in the direction of rotation of the cam 18e. Further, the base portion is held by a contact base 45 fitted into the second case element 12a (third case element 13e in the case of the second signal generator).

Next, the biasing mechanism 42 is for biasing the cam 113e toward the normal position shown in FIG. 6, and is composed of a biasing cam 48 and biasing springs 49 and 49. The biasing cam 48 is made of an insulating material such as synthetic resin, and is rotatably mounted on the bearing 16e (in the case of the second signal generator, the bearing provided on the third case element). The outer periphery of the cam 48 is provided with a spring abutment 50.51 and interlocking teeth 52 that mesh with the interlocking teeth 44 of the cam 186.

The biasing springs 49, 49 contact the spring contact portions so and st to bias the cam 48 to the neutral position shown in Fig. 6.8. Pieces 24e + 24e are used. However, an independent spring other than the contact piece 24e may be used.

In the pulse generator having the above configuration, since the clutch element 39 is engaged with the clutch element 36 in the state shown in FIG. 5, when the operating shaft 286 is rotated in this state, a pulse signal is generated from the second signal generator 4e. Obtainable. On the other hand, when the operating shaft 28e is pushed in against the biasing force of the spring 40, the clutch element 38 engages with the clutch element 35. If the operating shaft 28e is rotated in this state, the first signal generator 3e
A pulse signal can be obtained from.

When the signal generator is operated as described above, when the rotating body 29e is rotated by the driving body 37, the cam 18"e' is rotated once and the bridging piece 22e is moved as in the above embodiment.
bridges the contact pieces 24e and 25e intermittently. In that case, since the positions of the tips of the contact pieces 24e and 25e are different in the rotating direction of the cam 18e as described above, the contact piece 25e contacts the bridging piece 226 first, and the subsequent contact piece 25e contacts the bridging piece 226.

It should be noted that parts that are considered to have the same or equivalent structure as those in the previous figure in terms of function are given the same reference numerals as in the previous figure with the letter e, and redundant explanations are omitted.

(Effects of the Invention) As described above, in the present invention, it is possible to obtain a pulse signal by rotating the operating body 5. When obtaining the pulse signal, for example, the operating body 5 is rotated. First, the first signal generator 3 generates a pulse signal by rotating it in the forward state, and then by moving the operating body 5 backward and rotating it, the second signal generator 4 is generated. Therefore, it is possible to generate a pulse signal different from that described above, and there is an effect that two different types of pulse signals can be generated with extremely good operability.
