Abstract

A vehicular pointer-type residual quantity meter comprises: a display panel that has a scale part which allows a driver to recognize a residual quantity, and a non-scale part that differs from the scale part; a pointer unit that is disposed behind the display panel; a pointer driver body unit that carries out a movement of the pointer unit in a real space; and a control unit that controls the pointer driver body unit in so that the pointer unit indicates one of metering regions in the scale part in replay to a current residual quantity. The control part controls the pointer driver body unit so that when the residual quantity decreases to zero, the pointer unit moves from a metering region corresponding to a zero residual quantity in a direction opposite to a metering region corresponding to a residual quantity value greater than zero to the non-scale part of the display panel.

Claims

1. A vehicular pointer-type residual quantity meter comprising:

a display panel that has a scale part, the scale part allows a driver to recognize a residual quantity, and a non-scale part that differs from the scale part;

a pointer unit that is disposed behind the display panel;

a pointer driver body unit that carries out a movement of the pointer unit in a real space; and

a control unit that controls the pointer driver body unit whereby the pointer unit indicates one of metering regions in the scale part in replay to a current value of the residual quantity, and the control unit controls the pointer driver body unit whereby, when the residual quantity decreases to zero, the pointer unit moves from a metering region corresponding to a zero residual quantity in a direction opposite to a metering region corresponding to a residual quantity value greater than zero to the non-scale part of the display panel,

the pointer unit includes a pointer that forms an illuminating section,

the vehicular pointer-type residual quantity meter further comprises a light source for the illuminating section,

the scale part includes a light-transmitting member that is capable of transmitting light from the light source,

the non-scale part includes a light-shielding member that is capable of shielding light from the illuminating section,

when the residual quantity decreases to zero, the pointer moves from a position behind the light-transmitting member to a position behind the light-shielding member so as to prevent the pointer from being recognized by the driver,

the pointer includes an oblong pointer body and a pointer body extension unit disposed adjacent to the pointer body,

the pointer body and the pointer body extension unit together form the illuminating section, and

immediately before the residual quantity decreases to zero, the pointer body and the pointer body extension unit remain recognizable by the driver, and when the residual quantity decreases to zero, the pointer unit moves to the non-scale part so as to prevent the pointer body and the pointer body extension unit from being recognized by the driver.

2. The vehicular pointer-type residual quantity meter according to claim 1,

the control unit controls the light source in such a manner that the illuminating section is lighted on when the residual quantity is not zero, and the illuminating section is lighted off when the residual quantity decreases to zero.

3. The vehicular pointer-type residual quantity meter according to claim 2,

when the residual quantity decreases to zero, the control unit lights off the illuminating section after the movement of the pointer unit is completed.

4. The vehicular pointer-type residual quantity meter according to claim 1,

the control unit controls the pointer driver body unit such that when the residual quantity decreases to zero, the pointer unit gradually moves to the non-scale part.

5. The vehicular pointer-type residual quantity meter according to claim 1,

the control unit controls the pointer driver body unit such that when the residual quantity decreases to zero, the pointer unit rapidly moves to the non-scale part.
