Description

【0001】
【発明の属する技術分野】
本発明は、ペン型カウンタに関する。
【0002】
【従来の技術】
サンプルの数の計測作業は、多くの場合、作業員が頭の中で数を計測したり、ハンドカウンタを用いて計測したりしていた。そのため、当該作業中には、作業場所を途中で離れたり、計測数を間違えたりすることがよくあった。また、他の作業員に話しかけられたりして、計測作業が中断されたりした場合には、それまで計測した数やサンプルを忘れることも多々あり、最初から計測作業をし始め直さなければならないということもあった。
【0003】
【発明が解決しようとする課題】
このような状況のもと、本発明者らは、サンプルの数の計測作業を、より容易に行い、また当該作業を途中で中断しても、最初から作業をし直すことなく、容易に中断したところから再開できる計数器(カウンタ)について鋭意検討したところ、筆記部の被筆記体への押圧動作に応じて退動・進出する、筆記部が接続されたインク収容体の当該退動・進出動作をマイクロスイッチ等の検出手段で検出し、前記検出手段の出力に基づき、計数するペン型カウンタを用いることにより、容易に計数作業ができることを見出し、本発明に至った。
【0004】
【課題を解決するための手段】
すなわち本発明は、筆記部と、前記筆記部に接続され、前記筆記部の被筆記体への押圧動作に応じて退動・進出するインク収容体と、前記インク収容体の退動・進出動作を検出する検出手段と、前記検出手段の出力に基づき、計数する計数手段とを備えてなるペン型カウンタを提供するものである。
【0005】
【発明の実施の形態】
以下、本発明について、図面を参照しながら説明する。図1に、本発明のペン型カウンタの模式図を示した。本発明のペン型カウンタ1は、筆記部2と、前記筆記部2に接続され、前記筆記部2の、被筆記体への押圧動作に応じて退動・進出するインク収容体3と、前記インク収容体3の退動・進出動作を検出する検出手段4と前記検出手段4の出力に基づき、計数する計数手段5とを備えている。筆記部2とインク収容体3が接続されているため、本発明のペン型カウンタは、筆記可能であり、サンプル数の計測作業の際、対象となるサンプルに、目視可能な目印等を記入することができ、どこまでサンプル数を計測したかが、確認容易となっている。また、計測した数が、計数手段の表示部6に表示されるため、頭の中に計測した数を記憶しておく必要もなく、作業がより容易になる。また、途中で、計数作業を中断しても、前記のとおり、計数済みのサンプルと計測した数が目視できるため、該作業を最初からやり直す必要もなく、再開も容易である。
【0006】
筆記部2とインク収容体3と検出手段4は、通常ペン型のケース7内に保持されており、計数手段5が、前記ケース7外に設けてもよいし、ケース7に一体に設けてもよい。インク収容体3は、通常通常のその内部にインクが収容されている。図2に本発明のペン型カウンタの一実施態様を示したが、この実施態様では、検出手段4は、マイクロスイッチ41により構成されており、マイクロスイッチ41で検出された信号が、計数手段5に配線ワイヤ8を通して伝送されるようになっている。
【0007】
筆記部2を、被筆記体に押圧することにより、前記筆記体2と接続されたインク収容体3が、前記押圧力により、後退し、マイクロスイッチ41に当接する。マイクロスイッチ41は、インク収容体3の端部が当接すると、計数手段5に、オンの信号を伝送する。筆記部2を被筆記体から離すと、押圧力が開放されるため、インク収容体3は前進し、その端部がマイクロスイッチ41から離れる。マイクロスイッチ41は、インク収容体3の端部が離れると、計数手段5に、オフの信号を伝送する。計数手段5は、マイクロスイッチ41から伝送されるオンとオフの信号の一対を、1回として、表示部に回数を表示させる。
【0008】
マイクロスイッチにより検出手段が構成される場合、インク収容体3の端部が直接マイクロスイッチに当接すると、筆記部2の押圧力全てがマイクロスイッチに負荷されるため、マイクロスイッチの強度によっては、マイクロスイッチが破損しやすくなるため、図3に示すように、インク収容体3の端部とマイクロスイッチの間に、押圧力を緩和するための中間部材9および延長ロッド10を設けてもよい。
【0009】
図4に、検出手段4が、フォトセンサ42により構成された別の実施態様の検出手段部位の模式図を示した。インク収容体3の端部がフォトセンサのセンサ部に出入可能となっており、筆記部2が、被筆記体に押圧されると、前記押圧動作により、インク収容体3の端部が、センサ部に入り、端部を検出した検出信号が計数手段5に伝送される。筆記部2が、被筆記体から離れ、押圧力がなくなると、インク収容体3の端部がセンサ部から出、端部を検出しなくなると、検出信号を計数手段5に伝送しなくなる。計数手段5は、センサ部が検出した検出信号の有無の一対を、1回として、表示部に回数を表示させる。フォトセンサの構造にもよるが、検出孔内へインク収容体3の端部が出入可能となったセンサ部のフォトセンサの場合には、図5に示すように、インク収容体3の端部が前記検出孔に出入可能な程度に、該端部の径がすぼまった形状になっていてもよい。
【0010】
図6に、検出手段4が、圧電素子43により構成された別の実施態様の検出手段部位の模式図を示した。圧電素子43は、その変形許容空間431を覆うように、圧電素子支持体432に設けられている。インク収容体3の端部が圧電素子43に当接可能となっており、筆記部2が、被筆記体に押圧されると、前記押圧動作により、インク収容体3の端部が、圧電素子43に当接し、前記圧電素子43を湾曲させる。前記圧電素子43の湾曲により、筆記部の押圧動作を検出し、検出信号が計数手段5に伝送される。筆記部2が、被筆記体から離れ、押圧力がなくなると、インク収容体3の端部が圧電素子43から離れ、前記圧電素子43の湾曲が元に戻り、検出信号を計数手段5に伝送しなくなる。計数手段5は、圧電素子43の湾曲による検出信号の有無の一対を、1回として、表示部に回数を表示させる。
【0011】
マイクロスイッチにより検出手段が構成される場合と同様、圧電素子により検出手段が構成される場合も、インク収容体3の端部が圧電素子43に当接すると、筆記部2の押圧力全てが圧電素子に負荷されるため、圧電素子が破損しにくくするため、インク収容体3の端部と圧電素子の間に、押圧力を緩和するための中間部材9および延長ロッド10を設けてもよい。
【0012】
計数手段5は、図2のように、配線ワイヤ等の有線信号伝達手段により検出手段4と接続されていてもよいし、図7のように、例えば赤外線等を利用した無線信号伝達手段で検出手段4と結ばれていてもよい。例えばこの場合、検出手段4で検出した信号は、赤外発光回路11を介し発光素子12から出力される。発光素子12から出力された光信号は、受光素子13によって受信され、受信された信号が、変換回路14で変換され、計数手段に出力される。
【0013】
【発明の効果】
本発明によれば、サンプルの数の計測作業を、より容易に行い、また当該作業を途中で中断しても、最初から作業をし直すことなく、容易に中断したところから再開できる。また、試験の採点作業や漢字等の文字の画数を計数する作業においても、本発明のペン型カウンタを用いることにより、採点の集計や画数の計数が容易になる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a pen-type counter.
[0002]
[Prior art]
In many cases, the work of measuring the number of samples is performed by a worker counting the number in his head or using a hand counter. Therefore, during the work, the user often leaves the work place on the way or makes a mistake in the number of measurements. Also, if the measurement work is interrupted due to talking to other workers, the number of samples and samples taken so far are often forgotten, and it is necessary to restart the measurement work from the beginning. There were things.
[0003]
[Problems to be solved by the invention]
Under such circumstances, the present inventors have performed the work of measuring the number of samples more easily, and even if the work is interrupted halfway, the work can be easily interrupted without restarting from the beginning. After a thorough study of a counter that can be restarted from the place where the writing unit was pressed, the ink unit to which the writing unit is connected retreats and advances in response to the pressing operation of the writing unit on the writing object. The present inventors have found that the counting operation can be easily performed by using a pen-type counter that detects the operation by a detecting means such as a microswitch and counts the output based on the output of the detecting means.
[0004]
[Means for Solving the Problems]
That is, the present invention provides a writing unit, an ink container connected to the writing unit, which retreats and advances in response to a pressing operation of the writing unit on a writing object, and a retreat and advance operation of the ink container. Is provided, and a pen-type counter comprising: a counting means for counting based on an output of the detecting means.
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described with reference to the drawings. FIG. 1 shows a schematic diagram of a pen-type counter of the present invention. The pen-type counter 1 of the present invention includes a writing unit 2, an ink container 3 connected to the writing unit 2, the ink container 3 retreating and advancing in response to a pressing operation of the writing unit 2 on a writing object, and A detection unit 4 for detecting the retreat / advance operation of the ink container 3 and a counting unit 5 for counting based on the output of the detection unit 4 are provided. Since the writing unit 2 and the ink container 3 are connected to each other, the pen-type counter of the present invention is writable, and, when measuring the number of samples, writes a visible mark or the like on the target sample. It is easy to confirm how far the number of samples has been measured. Further, since the measured number is displayed on the display unit 6 of the counting means, it is not necessary to store the measured number in the head, and the work becomes easier. Further, even if the counting operation is interrupted in the middle, the counted sample and the measured number can be visually observed as described above, so that the operation does not need to be restarted from the beginning and restarting is easy.
[0006]
The writing unit 2, the ink container 3, and the detection unit 4 are usually held in a pen-shaped case 7, and the counting unit 5 may be provided outside the case 7, or may be provided integrally with the case 7. Is also good. The ink container 3 usually contains ink therein. FIG. 2 shows an embodiment of the pen-type counter of the present invention. In this embodiment, the detecting means 4 is constituted by a microswitch 41, and the signal detected by the microswitch 41 is supplied to the counting means 5 Is transmitted through the wiring wire 8.
[0007]
When the writing unit 2 is pressed against the writing body, the ink container 3 connected to the writing body 2 is retracted by the pressing force and contacts the microswitch 41. The micro switch 41 transmits an ON signal to the counting means 5 when the end of the ink container 3 comes into contact. When the writing unit 2 is separated from the object to be written, the pressing force is released, so that the ink container 3 moves forward, and its end part is separated from the microswitch 41. The microswitch 41 transmits an off signal to the counting means 5 when the end of the ink container 3 is separated. The counting unit 5 sets the pair of the ON and OFF signals transmitted from the microswitch 41 to one time and causes the display unit to display the number of times.
[0008]
When the detection means is constituted by a microswitch, if the end of the ink container 3 directly contacts the microswitch, the entire pressing force of the writing unit 2 is applied to the microswitch. Therefore, depending on the strength of the microswitch, Since the microswitch is easily damaged, an intermediate member 9 and an extension rod 10 for reducing the pressing force may be provided between the end of the ink container 3 and the microswitch, as shown in FIG.
[0009]
FIG. 4 shows a schematic diagram of a detecting means portion of another embodiment in which the detecting means 4 is constituted by a photo sensor 42. The end of the ink container 3 can enter and exit the sensor unit of the photosensor. When the writing unit 2 is pressed against the writing object, the end of the ink container 3 is moved by the pressing operation. Then, a detection signal for detecting the end is transmitted to the counting means 5. When the writing unit 2 separates from the object to be written and the pressing force disappears, the end of the ink container 3 comes out of the sensor unit. When the end is no longer detected, the detection signal is not transmitted to the counting unit 5. The counting unit 5 sets the pair of the presence or absence of the detection signal detected by the sensor unit as one and displays the number on the display unit. Although depending on the structure of the photosensor, in the case of the photosensor of the sensor unit in which the end of the ink container 3 can enter and exit the detection hole, as shown in FIG. May have a shape in which the diameter of the end portion is reduced to such an extent that the end can enter and exit the detection hole.
[0010]
FIG. 6 shows a schematic view of a detecting means portion of another embodiment in which the detecting means 4 is constituted by the piezoelectric element 43. The piezoelectric element 43 is provided on the piezoelectric element support 432 so as to cover the deformation allowable space 431. The end of the ink container 3 can be brought into contact with the piezoelectric element 43, and when the writing unit 2 is pressed against the writing object, the end of the ink container 3 is moved by the pressing operation. 43, and the piezoelectric element 43 is bent. The pressing operation of the writing portion is detected by the bending of the piezoelectric element 43, and a detection signal is transmitted to the counting means 5. When the writing unit 2 separates from the object to be written and the pressing force disappears, the end of the ink container 3 separates from the piezoelectric element 43, the bending of the piezoelectric element 43 returns to its original state, and the detection signal is transmitted to the counting unit 5. No longer. The counting unit 5 displays the number of times on the display unit with one pair of the presence or absence of the detection signal due to the bending of the piezoelectric element 43 as one time.
[0011]
Similarly to the case where the detecting means is constituted by the microswitch, also in the case where the detecting means is constituted by the piezoelectric element, when the end of the ink container 3 comes into contact with the piezoelectric element 43, all the pressing force of the writing unit 2 becomes piezoelectric. An intermediate member 9 and an extension rod 10 for reducing the pressing force may be provided between the end of the ink container 3 and the piezoelectric element to prevent the piezoelectric element from being damaged because the element is loaded.
[0012]
The counting means 5 may be connected to the detecting means 4 by a wired signal transmitting means such as a wiring wire as shown in FIG. 2, or may be detected by a wireless signal transmitting means utilizing infrared rays or the like as shown in FIG. It may be connected to the means 4. For example, in this case, the signal detected by the detection unit 4 is output from the light emitting element 12 via the infrared light emitting circuit 11. The optical signal output from the light emitting element 12 is received by the light receiving element 13, and the received signal is converted by the conversion circuit 14 and output to the counting means.
[0013]
【The invention's effect】
According to the present invention, the work of measuring the number of samples can be performed more easily, and even if the work is interrupted in the middle, the work can be easily restarted from the place where it was interrupted without restarting the work from the beginning. In addition, in the work of scoring a test and the work of counting the number of strokes of characters such as kanji, the use of the pen-type counter of the present invention facilitates the counting and counting of strokes.
